Abstract:
It is demonstrated that in fullerene C$_{70}$, which can be considered as a deformed fullerene C$_{60}$ in some mean sense there is a withdrawal of an Electrodynamical forbiddance of a strong quadrupole light-molecule interaction, which is realized in the fullerene C$_{60}$. This situation occurs because of the reduction of symmetry of C$_{60}$ from the icosahedral symmetry group $Y_h$ to the group $D_{5h}$. The withdrawal results in appearance of the lines in the SERS spectra of C$_{60}$, which are forbidden in usual Raman scattering and are active in the infrared absorption spectra. The experimentally measured SERS spectra of C$_{70}$ demonstrates existence of such lines that strongly confirms our ideas about the dipole-quadrupole SERS mechanism.
